My only history setting is "Move to end".
If I execute "echo foo" and then, perhaps several times, press

Code:

"e" <Up> Enter

to re-execute the command, sooner or later, TCMD will not draw the entire command. After the <Up> the current command line will show 1 character (I've also seen 0), with the caret in position 9. <Enter> will execute "echo foo" again. Below, it happened the third time I pressed "e" <Up>.

Here's another where, after interrupting the ping, I pressed "p" <Up> to execute it again.

I tried this 250 times and was unable to reproduce it. The video drawing code is the same in v18 & v19.

It pretty much has to be either a Windows API failure or a video driver bug. Given your disinclination to update either, it would be hard to pin down. Try detaching the tab and see if it appears correctly in the console window. If not, it's a conhost or video driver problem.

It looks OK in the console after it's detached. I couldn't duplicate it on lucky (via RD). There's a gadget in one of my plugins that tries to keep the cursor off the last line of the visible rectangle. I'll try (later) disabling that to see if it's causing the problem.
